摘要： A temperature detection hole 12 having a bottom, which is sealed against the inside of the battery case 3 while being open to the outside, is formed in the battery case. The bottom wall 12a of the temperature detection hole is in contact with or in close proximity to the elements for electromotive force. Engaging hooks 14 are formed on lateral portions of the temperature detection hole 12 of the battery case 3, while a temperature sensor 13 is provided with elastically deformable engaging flanges 21. When the temperature sensor 13 is mounted removably in the temperature detection hole 12, the elastic restorative force of the engaging flanges 21 that are engaged in elastic deformation with the engaging hooks 14 is applied to the temperature sensor 13. The sensor end 13a of the temperature sensor 13 is thereby pressed against the bottom wall 12a of the temperature detection hole 12.

摘要： A power supply unit capable of simplifying the structure of a battery case and improving the cooling efficiency by increasing the cross sectional area of a coolant passage. A power supply unit includes a battery case; a plurality of battery modules disposed in parallel, each battery module is composed of three cells connected in series in a row, and the front end and the rear end of the battery module are held by the front part and the rear part of the battery case; a cooling fan for forcing a cooling air to flow in the passage between the neighboring battery modules; a shielding plate for shielding the cooling air from the battery module, which is placed at the upstream side of the passage and; a rectifying fin for increasing the flow rate of the cooling air, which is placed at the downstream side of the passage.
